IMPROVEMENT IN COPYlNG-PRESSES.

Specification forming part of Letters Patent No. 202,756, dated April23, 1878; application filed April 3, 1678.

To all whom it may concern:

Be it known that I, EDWARD H. T. 0. RATE, of Newark, in the county ofEssex and State of New Jersey, have invented certain new and usefulImprovements in Copying-Presses; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to which it appertains to make and usethe same, ref erence being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of thisspecification, and in which Figure 1 represents a perspective view of mycomplete invention, and Fig. 2 a detail view of the same.

Similar letters of reference occurring on the several figures indicatecorresponding parts.

My invention relates to an improved device for taking impressions orcopies of written matter; and it consists of a metallic base or stand,having vertically-slotted standards, at

the upper part of which are journaled a lower wooden roller and an upperflexible roller, each being provided with cog-gearing and operated by asuitable crank or handle, said standards being also provided withprojecting tables or platforms, all as will be hereinafter more fullydescribed, and pointed out in the claim.

Referring to the drawings, A represents the metallic stand, provided oneach side with vertically-slotted standards B, inwhich are journaled theupper flexible roller 0 and lower wooden roller D, each being providedwith cog-gearing a b on one side, and adapted for operation through themedium of the crank or handle E.

The projecting tables or platforms F are arranged at the front and rearof the rollers, and are provided on their inner lower ends with lugs c,which fit into correspondingly-shaped sockets d, formed on the standardsB during the'process of casting the same. The upper surfaces of thetables or platforms F, which are employed for supporting the matter tobe copied, are arranged on a level with the upper surface of the lowerwooden roller D, the upper flexible roller 0 being adapted to move upand down in the vertical slot in the standards B, to correspond to thethickness of the material which is to be passed between the rollers,suitable pressure being applied to the upper flexible roller 0 by meansof the thumb-screws G in the upper part of standards B operating uponthe sliding bearing e upon the upper part of the journals of theflexible roller 0.

The construction of my invention being as already described, it will beobserved that in the operation of the same the written matter is firstplaced upon a sheet of oiled paper or bristol-board, and the thindampened sheets of paper upon which the impression or copy is to betaken placed over that, and another sheet of oiled paper over the whole,which is then run between the two rollers C D by operating the crank E,thereby securing a perfect fac-simile of the written matter, and in anydesired number.

In place of the two rollers O D, I contemplate using, if deemeddesirable, two upper flexible rollers and two wooden rollers beneath,and so adjust the upper flexible rollers as to permit of the easypassage between the upper and lower rollers of an ordinary letterpressbook, so as to enable me to secure impressions or copies of writtenmatter in a bound volume or book. The pressure requisite for securing aneven copy or impression can be regulated at will by means of thethumbscrews G.

The advantages of my invention, particularly where rapid copying ofmanuscript, letters, or other written matter is desirable, will bereadily apparent without a more minute description, inasmuch as itcombines, in its construction and operation, a high degree of simplicityand economy with a ready adaptation to the purpose contemplated.

1 am aware that the arrangement of an upper and lower roller in suitablebearings, and operated by a crank for copying purposes, is not new initself; nor do I desire to claim such a construction broadly; but

What I do claim as new and useful is-- In a copying-press constructed asherein described, the combination of the base A, pro- In testimony thatI claim the foregoing as my own invention I affix my signature in presence of two witnesses.
